We split them up this way because the roads and auqaducts are most important because that is how people get around and get water. The aide for plebiens is the second most important because the plebiens are the farmers and they grow food for the people of Rome and their health is also important. The military is third important because it protects Rome in battle. The government saleries are fourth important because if the people in the government don't get paid, they won't work for the government. The entertainment is fifth important because without entertainment, the Romans will get bored and start to revolt against other people.
